Gastric bypass surgery information

The first gastric bypass procedure was performed in 1994, and the method of performing this type of operation has developed over time with the emergence of new surgical technologies, to become safer and more effective compared to the older techniques used in the past. Gastric bypass is a great option when compared to the rest of weight loss procedures, as it results in more weight loss than adjustable gastric banding or gastric sleeve procedures do.

The advantage of this operation is that the weight loss it induces remains constant over time and the patient is less likely to regain weight after they have lost it.

Gastric bypass surgery definition

Gastric bypass surgery helps obesity patients lose weight by both restricting the amount of food a person consumes and reducing the total amount of calories absorbed by the gastrointestinal tract. Gastric bypass procedure also induces some hormonal and physiological changes when food doesn’t pass through the duodenum –first part of small bowel- , as it decreases ghrelin levels, which are the hunger hormone, and increases the levels of leptin hormone, which is the satiety hormone, thereby decreasing the feeling of hunger and suppressing appetite, restricting the amount of food the patient consumes

Types of Gastric bypass surgery

SASI is one of the most recent types of gastric bypass operations, and it has been called by this name because it is through which the path of food entering the stomach is divided into two tracks:

Laparoscopic SASI bypass involves performing two simultaneous procedures, namely gastric sleeve, and gastric bypass, where the process is divided into two stages:
